If you're invested in a TV series, it can be tough watching the protagonist making a decision you know to be dumb. If three protagonists all make a dumb decision -- the same dumb decision -- it can be agonising. The latest episode of The Walking Dead features three of our "heroes" all enacting doomed, stupid plans. And despite it being yet another needlessly 90-minute episode, only one of them even got close enough to actually fail.
